FIELD: testing equipment. SUBSTANCE: invention is related to installations to test articles for impact loads. Bed for impact test has frame, rotor, sockets arranged on periphery of rotor where strikers in the form of balls are inserted. Internal surface of frame also has sockets where strikers in the form of balls are placed. Bed provides for multiplicity of action and ensures loading of tested ball with equal probability in all its points and makes testing more realistic, close to operational conditions existing in ball mills by velocities and stresses of collisions. EFFECT: increased reliability of testing. 1 cl, 2 dwg |
